Fire doors are one of the most critical elements of a building’s passive fire protection. When installed and maintained correctly, they help to contain fire and smoke, protecting escape routes and saving lives. But too often, they’re overlooked or fall into disrepair — putting buildings and occupants at serious risk.
If you’re a landlord, facilities manager, school leader or business owner, it’s your legal duty to ensure fire doors are compliant and functioning properly.
This article outlines the key things to check, common mistakes, and how IGB Ltd can help you stay compliant.
Why Fire Door Compliance Matters
- They buy time — slowing the spread of fire and smoke.
- They protect lives — giving people time to escape.
- They’re a legal requirement under the Fire Safety Order and the Building Regulations.
- They reduce liability — failure to maintain can lead to fines or prosecution.
Fire Door Compliance Checklist
Here’s what you (or your fire safety provider) should check:
1. Certification
- Is the door clearly marked with a certification label (usually on the top edge)?
- Does the door match the specification of the building’s fire strategy?
2. Door Gaps
- Are gaps around the top and sides no more than 3-4mm?
- Is the gap at the bottom no more than 8mm (or as specified for the door type)?
3. Door Closers
- Does the door close firmly on its own?
- Is the closer adjusted to prevent slamming or incomplete closure?
4. Intumescent Seals
- Are the seals around the door and frame intact?
- Are they continuous, undamaged, and not painted over?
5. Hinges and Fixings
- Are there at least three secure hinges?
- Are screws tight and not missing?
6. Signage and Glazing
- Is the correct fire door signage present (e.g. “Fire Door Keep Shut”)?
- If glazed, is the glass fire-rated and properly sealed?
7. No Obstructions
- Is the door free from door stops or wedges?
- Is the doorway clear at all times?
8. Condition and Maintenance
- Is the door in good condition with no damage, warping, or splits?
- Has it been inspected recently? (Ideally every 6 months for non-domestic buildings)
Common Compliance Failures
- Missing or fake certification labels
- Doors that don’t fully close
- Gaps that are too wide
- Damaged or painted-over seals
- Poorly fitted hardware or after-market changes
These faults can invalidate your fire protection and expose you to legal risk.
